Theya re indeed from Schutz, as pointed out! They were bought at the Schutz shop in Campinas Iguatemi Shopping center in mid April.

Schutz NY opened recently (I was there in August and they hadn’t opened yet), so I doubt they will have it there or know about it. Best bet is probably to contact their web sales team in Brazil http://loja.schutz.com.br/, they have a live chat on the site. Or you can contact via a form. They are quite active on social media too, so might be worth trying….
